AUTOMATIC STOP-MOTION FOR WOOL-COMBING MACHINES.

SPECIFICATION forming part of Letters Patent No. 564,912, dated July 28, 1896.

Application filed January 3, 1896. Serial No. 574,220. (No model.)

To all whom it may concern.-

Be it known that we, FRANK G. BERWIOK and SAMUEL HADFIELD, citizens of the United States, and residents of Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Im provements in Automatic Stop-Motions Applicable to Wool-Oombing Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

Our invention relates to improvements on combing-machines in use in worsted mills; and the object of our invention is to provide a mechanism in part attachable to the frame of the comb with its cooperative parts attached to the shipper-rod for the purpose of automatically stopping said comb at such times as the sliver of wool which is being manipulated becomes separated or severed, and thus prevent injury to the pins through which the combing of the wool is accomplished.

We attain our object by the mechanism illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a front view in perspective of sufficient portions of a comb-frame and the bed thereof to subserve an intelligent description of our invention thereto attached. Fig. 2 is a similar enlarged view from the rear of the automatic throw-ofi features of our improvement. 7 I

Similar characters designate like parts throughout the views, referring to which The numeral 1 designates the shaft of the ions 11 and 12 and the intermediate smaller gear 13. Motion is thus transmitted from the pulley 4 to the worm 10, the organized tSSGID;

blage receiving its motion through the bet; from the shaft 1, previously alluded to.

we now refer to the shipper-rod 14, upon which is adjusted the worm-rack and the sleeve 17, which are both loose upon said rod 14 while retained in their appropriate positions, and restrained from independent longitudinal movement by their fixed collars 16, the normal position of the worm-gear 15 being disengaged, as illustrated. A threaded rod 18 depends from the hub of the wormgear 15, and supports the adjustable counterweight 19, whose office is to poise said gear 15 normally, this weight being regulated to equiponderate the vertical rod 20, adjustably suspended from the short arm 21, also projecting from the same hub and in a position at right angles to the threaded rod 18. The appurtenances to rod 20 comprise two sliding hangers 22, vertically adjusted and respectively secured by screws 23, said hangers in turn loosely suspending each, a hanging wire 24 terminating at itslowest end in a refiexed form and provided with an antifriction terminal 25 of rubber, porcelain, or other suitable material, which is supported in proximity to the funnels by the sliver of wool 26 as long as the latter remains intact or unbroken with the comb mechanism running smoothly. W'hen, however, the sliver 26 is severed from any cause, the suspended Wire or wires 24 impart their additional Weight to the vertical rod 20, which obviously overcomes the counterweight l9,and consequently semirotates the worm-rack 15 into mesh with the rotating worm-gear 10, thus actuating longitudinally the shipper-rod 14 with its attached shipper, and through it the belt is moved upon the loose pulley 3, thus stopping the comb.

We will now revert to the two-track automatic device through which the rack 15 is thrown ofi from worm 10. (See Fig. 2.) The loose sleeve 17 previously mentioned is provided with a short projecting rod or traveler 27 (in a similar position as the arm 21 previously described) resting below the loop 28 and upon the lower supporting-track 29, of

which it forms a part, so=long as the comb runs properly and the sliver of wool is integral. The longitudinal portion of said track 29 is interrupted by a short and quick incline 3O integral therewith and adjacent to the refleXed shank 31, provided with the slot 32, by which it may be adjustably secured by the bolt and nut 33 against the frame-piece 9. 34 designates the flexible upper track bridging the highest end of said incline, and the terminal of the loop 28 to which said flexible track is secured. Said sleeve 17 is further provided with a lug 35, which coacts with a flange 36, forming a part of rack 15, whose office will be presently described.

To illustrate the operation of our automatic safety device, the sliver 26 is supposed to be severed, the wire or wires and described connections fall to the positions indicated by dotted lines, Fig. 1, their additional weight augmenting the weight of the rod 20 brings therack 15 into mesh with worm the flange 36 consequently turning backward in juxtaposition to the lug 35, the traveler 27 resting upon track 29. From. this position the shipper-rod 14, actuated by the worm 10 through the rack'15, carries the traveler 27 along to the foot of the incline 30 in the path of the dotted line and arrows, Fig. 2. sition the belt 35 is already thrown upon the loose pulley 3. The rack 15, however, has sufiicient further action (without disturbing the belt or pulley 3) to raise the traveler 27 to the top of incline 30, past the free end of the flexible track 34, so that itrests upon it momentarily. Meanwhile, in mounting said incline 30 the traveler 27 has semirotated the lug 35 forward again against the flange 36, which action releases the rack from the worm 10, the counterweight overcoming the weight of the now suspended parts, previously instrumental in bringing said rack in the path of the worm, as hereinbefore described. The machine-operator having reunited the sliver, restores the wires 24 and their terminals 25 to a proper position as formerly upon the sliver, and manually ships the belt again upon the fast pulley 2, the traveler 27 of course moving from its rest along the flexible track 34, being upheld thereby until it reaches the loop 28, whence it falls to its original position on 29, as illustrated. The counterweight 19, upon the suspension of the terminals 25 upon the sliver, again obviously exerts its influence to hold the rack 15 in its normal position on the shipper-rod 14, while the lug falls away from the flange 36'on the descent of the traveler 27 to its place of rest 29, as previously shown.

In the practical construction of our invention we do not desire to restrictourselves to the precise form of the several devices illustrated and described, but may employ therefor substantially the equivalents which would be within the fair scope and spirit of our invention. I

Having thus described the operation and construction of our improved invention. we

desire to secure by Letters Patent of the 'United States, and we claim--= In such a po- 1. In a combing-machine, the combination of the comb-driving shaft, fast and loose pulleys mounted thereon, a bracket connected to the framing, apulley 6, and worm mounted on said bracket, gearing connecting the same, said pulley 6 having a belt connection with said driving-shaft, a belt-shifter and a rod carrying the same, a rack on said rod and means controlled by the sliver for throwing said rack into engagement with the worm upon the breakage of the sliver to thereby shift the belt, substantially as described.

2. .In a machine for wool-combing, the fast and loose pulleys, the revoluble shaft driving said pulleys, the shipper rod and means thereon under control of the worm-rack for shifting the main belt to the loose pulley, the said worm-rack and the main belt, in combination therewith, the small belt-pulley 4 deriving motion from the main shaft, the worm, the means for transmitting motion from the pulley (5, to actuate the worm, and the wormrack carried by the shipper-rod having two hangers connected thereto, the two hanging wires suspended thereby provided with antifrictional terminals at their lower ends adapted to be supported upon and by the sliver of wool while the functions of the comb are uninterrupted, substantially in the manner and for the purpose set forth.
